"Me & Bobby Mcgee" (1st verse):
"Busted flat in Baton Rouge, headin' for the trains,
Feelin' nearly faded as my jeans.
Bobby thumbed a diesel down just before it rained,
Took us all the way to New Orleans.
Took my harpoon out of my dirty red bandana
And was blowin' sad while Bobby sang the blues,
With them windshield wipers slappin' time and
Bobby clappin' hands
We finally sang up every song that driver knew…"

For seamen the call of "Harpoon!" is a call of distress when a particularly dangerous sea monster is approaching their vessel. In modern culture this is used by young males to communicate their concern for an inebriated friend being attracted to a morbidly obese or outrageously unattractive female or transvestite.
